By ALL means, get a bigger CARB!!!

Heck,, I dunno,, wouldnt wanna see ya blow it up,, if you gotta reduce the boost to get it running right, that mite just be the smart move. Can ya Re-gear the blower & slow it down?

Quick update. I hunted out a smaller pulley from the wrecker yard. Went from a 100mm to a 92mm pulley. This has reduced the boost from spiking at 15psi to 11psi. When I whip the throttle open the boost spikes up to 11psi and settles to 7psi. Which is good. No more detonation.

I've got the jetting pretty sorted methinks. I'm running a 12.5 (VM) pilot in the CV with 2 tiny washers in place of the white spacer (no washers caused fuel to seep out from the needle constantly) and a 190 main.

Goes well, but I've noticed that cruising slowly into a corner in 2nd and then opening the throttle when the revs are low can cause the motor to cut out... might need to tweak something there.

It's surprising how smooth and instant the power is, and how quickly I've just gotten used to it.

Not a lot of riding of any significance yet. I've just taken it around the streets, to a mates house a few times, around the streets some more. It's quite loud and I get a lot of angry looks from the public.

Speeds.. probably up to 80km/h whats that for you yankies.. 50mph? I'm increasing the speeds incrementally as I'm listening for any detonation and watching my air/fuel gauge closely.

Seat of pants. The SC delivers instant pull, so there is no lag or anything like that like a turbo. It's more like riding a larger displacement bike. First gear seems pretty short, I boost off in first and hook second hard (to avoid the quite obvious savage neutral) then it pulls hard in 2nd and I usually run out of road and have to slow down by 3rd.  

I thought the SC would make a loud whine like a hotrod but it doesn't. You can't really hear it mainly over the loudness of my drag-pipe. Which is still too loud.

It's quite hard to measure the performance yet. It was off the road for so long while I built it that I've almost forgotten what it was like before. I would like to put it on a dyno to see what it's actually producing.

I'm still slightly concerned with the heat. I've been thinking back towards that oil-cooler thread again.. should I.. or shouldn't I

Hope you have a friendly WOF person, or aren't you going to bother?

From the looks of it a standard sav with exhaust and carb mods nets around 32hp at the rear wheel

Can anyone tell me what the maximum dyno proven power output for a modified savage is from this site?

Ok I'm back. I was right about the savage CV carb being too small, even with the largest jets it simply couldn't flow the air required. I starting tinkering with a SU HIF6 (44mm) which was massive.. and heavy! I quickly gave up on that when the throttle shafts were leaking and I didn't want to spend money on it knowing it was probably too large.

Got myself the popular Keihin CV40 off a Harley (40mm). Threw a jet kit in it guessing the settings and took bike out and holy crap what a difference it made.  

It's another beast now. 1st gear is short, launch and change then a HUGE pull in second and you've run out of street. Boosting in 3rd and I'm in loss of license speeds. I'll need to take out out somewhere decent for a proper strop. But I'm over boosting again, I'd put a smaller pulley on to reduce boost, but now with the larger unrestricted carb I'm back to making too much boost (15-20psi). So I'll like to pull that back again if I can.

It goes hard enough to impress my mate who rides a Honda VFR800 Interceptor..

Thank god or someone that no one from MOPP (Ministry of Petty Prosecutions) or MOOC (Ministry of Offence Creation) is likely to read your posts Mr Marshall.
