Title pretty much.
I can start this bike up without the choke, Just a little gas for 5-8 seconds and then it idles up to temperature perfectly fine.
Accelerates fine and I can get up to about 110 in 3rd gear, 4th Gear will let me up to 120 but the RPM’s drop to 10k.
5th Gear tops out at 8.5k and 6th Gear won’t go above 6.5k RPM’s
Keep in mind this is under load at speed, sitting still the bike idles and revs fine.
I believe the issue is something to do with the ram air.
Originally I didn’t have the ram air hooked up because I was still tuning the carbs. Even without the ram air I can get the bike to 120mph but not faster. I had to buy some new hose for the bowl pressure line.
If I had to take a guess it feels like it’s running rich when it hits the 120 mark. The engine bogs and will sometimes cut out.
The Pilot Screws are set at 3 turns out.
I have a K/N air filter, I believe the jets/needle may also be a stage1 dyno Kit.
Stock mufflers and pipes as well.
Here’s some pictures of the carbs and different areas on the bike encase anyone spots anything important that is needed.
Later today or tomorrow I’ll be taking the carbs off again to try and identify the jet sizes and compare those to the factory size I’ve had a lurking suspicion that the main jets may be too small or large.
