As its been a few years since i had my bikes on track can anyone recomend a tried and tested oil for a highly tuned 3tj race bike??

A road bike I'd say a straight 10-40w semi syth oil to avoid clutch slip, but a race bike is different ... obviously.

Im using Yamalube 10 40 semi synth. in my 3tj 600 conversion that i use for track days. Im told its made by motul. I use semi instead of fully synth as i have had clutch slip problems in the past!

all ways used morris's semi syn, or silkolene semi, no probs, a friend uses minral oil & changes it after every other meeting, recon''s its best ! but goes throu 2 motors a year, {so is it } any body else use it ? what state of tune is your 3tj may req fully synth, ?

hi m8 i use shell advance semi in both my tuned 3tjs and find it performs brilliant no probs at all .i buy mine through work from wurth who sell lots of good stuff to motor trade,we pay £60 for 4 4ltr tubs which is spot on for bike all dont you think.cheers hope this helps all the best daz

Im trying to do a deal with Morris for their semi-synthetic as i use their oils for work.

That shell oil sounds vey good though, i also use wurth at work so will be giving the rep a call 1st thing!

The highest tuned engine has: balanced/lightened crank, skimmed crank cases, skimmed barrel base, kent cams, gas flowed/ported head, triple angle seats, ram air, bdk system ect ect
