Lubrication tips


[edit] Introduction

Automobile parts stores have rows of materials. The Permatex company offers hundreds of different goos for thousands of different purposes. Another forum includes viscosity data for scores of fork oil products. This page is meant to show what Suzuki recommends (don't want to void the warranty on these decades-old machines!), but also what cheapskates have found that works to keep these forty-year old machines on the road. Where cheap products do not work, people can advise when to break out the wallet and pay for the pricey stuff. If there is disagreement on a product--great! Some oil may have served someone for decades and caused pistons to melt for someone else. It's okay to hear both sides of the story.

Please contact overrun or you can yourself add to this table or to the notes near the end if you have a product or procedure which helps to preserve these bikes or make them go faster.

[edit] Lubrication, gasket, and other tips table

Location S* Material Notes and threats
Engine / transmission
Transmission case + SAE 20W/40 multigrade oil
" Shell Rotella 15W/40 Affordable; made for diesel truck engines; Shell claim to have passed the Japanese Automotive Specifications Organization (JAS0) MA [and now MA2] specification which has a section for wet, multiplate clutches. Shell makes an affordable synthetic oil, Rotella T6, which supposedly also passes the JASO-MA [and now MA2] specification.
" Automatic transmission fluid Often used by racers. May help to swell up seals a bit so they will continue to seal.
CCI oil reservoir + Suzuki CCI Super Oil or non-dilutent two-stroke oil
" JASO-specification oil In 1994, the Japanese Automotive Standards Organization (JASO) devised a specification for two-stroke motorcycle engine oils which concentrates on lubrication properties, smokiness and "detergency." FD is the latest designation, and usually only a synthetic based oil can meet this specification. "Injector" oil can be mixed in the fuel tank (premix) or stored in a separate reservoir as on most Suzukis. Non-injector oil is not recommended for use with oil pumps. For a list of compatible oils, see *.PDF file 2T_EV_LIST.pdf at this JASO document page.
Engine rotating parts + Motor oil
Between split case halves + Suzuki bond No. 4

Side cover gaskets Grease on paper gaskets allows them to be reused but still seal
Spark plug threads Anti-seize compound
Spark plug boot
Exhaust flange nuts
Filthy chain parts
Chain and sprockets + Chain lube or motor oil
Fork tubes + 5W/20 oil or automatic transmission fluid (ATF)

[edit] A little bit about the JASO MA, MA1, and MA2 wet clutch specification

In 1998 the Japan Automobile Standards Organization (JASO) published oil specifications for motorcycles which share engine oil with a wet clutch and a transmission. The MA specification was for quality engine oils that offered good clutch friction and were still beneficial to the transmission. Our Suzukis do not need engine additives, but the gear and clutch portion of the specification is a welcome guidepost for us.

In 2006, MA1 and MA2 categories were added to the MA category. The stated reason for the change was the prevalence of catalytic converters on motorcycles. The zinc and phosphate engine additives (ZDDP has been around since the 1940s) are beneficial to four-stroke valvetrains, but are harmful to the catalytic converter.

So far (from the two-stroke perspective), who cares? The MA2 spec is for low-ZDDP, but it has higher clutch friction values than the MA1 spec, which has lower friction and higher allowed levels of ZDDP.

Amsoil helps us a bit here. They tend to shy away from specs, perhaps because they believe their oil to be superior and perhaps because as a small company they would go bankrupt if they kept up on all the required paperwork for all the certifications. Amsoil offers two oils that correspond roughly to the MA1 and MA2 specifications. The lower clutch friction oil is made for smooth shifts, as on a street bike. The higher clutch friction oil is made for off-the-line starts, mud, and steep hill climbing.

One might wonder if ZDDP has an effect on clutch performance, and no one on the internet has come out and asked this question. For our Suzukis, the low-engine-additive, high clutch friction MA2 specification seems custom made. Not too many catalytic converters on our bikes, but we don't need the ZDDP either. If the shifting seems too sharp, we can go to MA1 and enjoy our zinc.

For a street bike owner with a catalytic converter, however, I suppose harsh shifts are what you are going to endure to keep your catalytic converter clean. Hard shifts and worn out camshafts....

If the ZDDP is not helping with clutch friction, then the specifications seem not to make much sense. But they do work in our favor if we are thrashing our clutches like good dirt racers.

I think a solution can be found in the fine print of the specification. If an oil meets some of the MA1 specification, and some of the MA2 specification, then it may be labeled, MA. So that means we are kind of back to pre-1998 where we had to read the label and pick and choose our priorities. A street bike owner with a catalytic converter might want smooth shifting and low-ZDDP MA-rated oil.

So might a two-stroke Suzuki owner who wants softer shifts but doesn't need heavy engine additives.

[edit] A note on JASO compliance

Many manufacturers claim that their product meets one of the JASO specifications, but they are not on the official JASO list. JASO participants are required to test their own product and send in the results. By stating that a product exceeds the specifications, we can presumably trust that the company is honest in the testing. Some companies offer to honor warranty claims even though they have not filed the JASO paperwork.

[edit] Template for adding new table rows

If you paste this block in the correct place (|- represents the start of the second through final row), you will get a new blank row. If you add text in front of the <!--, it will show up. Adding ''' (three single quote marks) before and after the first line will embolden the text in that cell.

   | <!-- Location -->
   | <!-- S -->
   | <!-- Material -->
   | <!-- Notes and threats -->

To get a centered plus sign for factory-approved materials, paste this in the second column of a table row:

   | align="center"|+

If you are adding a new tip to an old subject, you can add a ditto mark in the first column:

   | align="center"|'''"'''

I can't stand wiki table code. Here are some things I will add later:

[edit] Gasket compounds of yore

[edit] Hylomar

Developed in the 1960s for Rolls-Royce aircraft engines. It works over a large heat range, is non-hardening, is easy to clean off of surfaces, and fills up to 0.010-in. It is used by many people in many applications. There are now quite a few companies licenced to produce it, and each has slightly different formulas and most seem to change product model names about every four years--it's a mess! Like someone took a beautiful painting of a daisy and spread Hylomar all over it.

Companies which have manufactured or marketed Hylomar include:

  • Hylomar Limited; Wigan, England
  • Hylomar USA, Inc.; Bloomfield Hills, Michigan
  • Lub-O-Seal Co, Inc.; Houston, Texas
  • Permatex Inc., Hartford, Connecticut (By 2009 they seemed to have worked out their differences with Hylomar Limited, but in 2013 the word Hylomar does not seem to exist on the corporate website.)
  • Valco Cincinnati Consumer Products; Cincinnati, Ohio

[edit] Toyota Seal Packing 102 (FIPG)

Part number 0295-00103. FIPG apparently stands for form-in-place gasket. This material is apparently cherished by those who must get a warped head to seal. Seen on Ebay as late as 2013.

[edit] ThreeBond

Established in 1955 in Tokyo, Japan. ThreeBond credits founder Osamu Ukumori with inventing the liquid gasket. Many Japanese and European motorcycle manufacturers and even motorboat motor manufacturers approve of Threebond 1207B.

Speculation abounds (abonds?) that the following products are merely rebadged ThreeBond products:

  • Hondabond
  • Kawabond 5
  • Suzuki bond No. 4
  • Yamabond

[edit] Elring

  • Dirko - Dirko RTV Sealant (Silicone) is beloved by Volkswagen mechanics and is used to seal cylinder bases.
  • Curil - When you step up to the Porsche 928 you forget your childish ways and are required to use Curil T. There is a Curil K2 which does not harden as much as the T.
