Engins Case Modifications

[geek]

If you just race at your local track that is fine. Try traveling 5-12 hours to a race. You would wish that you could service the forks and rods through the pan. Ask me how I know. Dar

Yes, I am spoiled running on Martin's track. Well prep'ed and smooth. We are lucky to have them in the area.

basic mods I know of

#1 holes under clutch basket - right in the casting circles - as big as it is and bevel the edges.
#2 trans access -- turns a 1 hour job into a 15 minute job.
#3 modify the sump pick up to draw from the rear of the engine.
#4 cut threads into the case mounting holes -- I use short 1/2' thick bolts to secure the engine instead of long stock ones
#5 rear upper engine mount Weld a 1/2" square piece of mild steel between the plates - or buy an APE unit.
#6 APE studs and nuts both on top and bottom
#7 smooth the fins off the oil pan and get a flush hex bolt for ground clearance
#8 with a outer bearing support for the countershaft a chain guide to direct a broken chain out and away from your cases -- got the idea from a dirt bike

#9 is to open the main bores to accept larger sleeves --if needed -
