I'm running a #150 main jet in a CVK 32mm carb. Anyone have an idea what size the pilot jet should be?
I'm having tough cold starts, and since it responded so well to the increased main jet, start looking at the idle circuit. Waiting on a set of pilots of diff sizes.
Thx.

No, I've tried w/the senor disconnected and same result (gauge pins redline as soon as key is on.) i just checked the connections, were a little corroded but cleaned up well.
It's probably a short. Think I'll try to find a universal gauge so I can monitor the motor.
Once I get that, I'll be able to take longer test drives and check on the rich/lean condition.

I pulled the thermostat out just in case.
The carb is jetted at 135, I'll be checking the plug & vacum to see if it's accurate. Might be a little lean: tough cold- starts. It has an electric choke which makes it a little tough to know when its off.
The joys of tuning!

Any ideas how to bleed the cooling system?
Rocked the bike back n forth, ran it w/the cap off until the level came up.
Anything I'm missing? Hate to be over-heating out on the road.
Thx.

I bought it w/no muffler, just a straight pipe out (not even a baffle.) So it's my theory that the heat just wore out the crank/piston. The piston had cracked and pieces were jamming the crankshaft.
Rebuild went well, just the over-heating problem. I think it's air in the system. I replaced the water pump, the 2 temp sensors, as well as the thermostat. New aluminum-friendly coolant mixed 50/50 was used.
I did not, however, bleed the system. I have both the CF Moto and Honda shop manuals but can't find any info on the subject (they both recommend bleeding the system, w/o any procedure.) Seems like an air blockage, because when the engine gets hot the radiator is still cold.
Also, I have not heard my fan kick on, and the temp gauge is always pinned to hot when the key is on. Not sure if a new temp sensor will fix that. I did replace the radiator mounted sensor.

Regarding the Scrappy Dog Performance Carburetor the fuel mixture screw is clockwise (in) to enrich. The thermostat housing must be removed for access.
It seems to be an air meter (turning in blocks air, richer mixture.)

Wow! I'll have to go over everything. I just rebuilt the crank/cylinder, replaced 'most' of the cooling parts.
Doesn't seem like its over-heating, but gauge doesn't seem to be working (not sure if it's related to the carb-area sensor I'm having problems with.)
Thx.

Can anyone tell me what might have caused this over-heated temp sensor? I have a new one on order, just wondering if something on the engine side could be responsible.
(Has good/level coolant, fresh oil, was only idling 1400rpms in air temp 70degrees. Stator is recent.)

Hello, I have a CF Moto V3/250 and a Scrappy Dog performance 32mm carb, and I'm having trouble w/the mix screw.
The best candidate is located on the side, below the enricher. Can someone confirm this? I will have to take off a water housing to get to it so I want to be sure.
Also, which way to turn, to enrichen idle?
(I have a stock air cleaner, but glass-pack muffler.)
Thx!
