Just wanting to benefit from the experience of anybody out there who’s running a modified Savage.
I’m now up and running with my motor, which will be putting a fair bit more power through the machine than original. It has:
Compression raised to 9.3:1 Ported head High lift cam (from lancer) VM carb (from Lancer) Freeflow pod air filter (from Lancer) Raask exhaust
Lancer ran a similar motor and saw 45hp at the wheel, but that was without the head porting and compression increase, so this engine could be putting out towards 50hp at the wheel – around double a standard Savage (I need to get it on a dyno some time and will post results, but more of that another day).
Two things I need to ask, to see if anybody out there has experienced these problems.
Despite using upgraded clutch springs, she's giving me clutch slip when I wind her on at top end – has anybody else found that with a tuned Savage? I guess when you're increasing an engine's output by so much it shouldn't be surprising. Anyone else encounter clutch slippage, even with uprated springs, on a tuned Savage? Is there a good kit available to further upgrade the clutch?
I also seem to be getting a 'jerking' through the transmission/drive when I start to wind some power on. Now, it may be the clutch juddering, or I wondered if maybe the extra torque was stretching the drivebelt and causing the teeth to catch – I can only describe it as feeling similar to a chain jumping teeth on a badly worn sprocket, but the belt is new and tight and the hubs are in good condition, so I don’t think the belt can be skipping teeth. I have no real experience with belts, but I seem to get noise from low behind my left ear when this happens, making me think the drivebelt isn't happy. I just fitted a new belt, and tensioned it so I can just turn it 90 degrees with fingers and thumb.
And pointers gentlemen?
