With most bikes it normally the springs that are below minimum length spec rather than the plates unless you have been abi=using them with drag starts etc !

The Barnett springs will definitely help hold things tight. But in traffic your hand will get very tired.

I just added a Nextgen clutch to my pregen motor, much lighter pull than the old one & appears to work well. I checked the spring free length & they were mid length between new & minimum spec & the clutch was supposed to by from a 20Kmile bike.

With the increase in displacement, are you still running the stock carbs? I assume so....

Any thoughts of upgrading the intake side of things?

He may be fuel injected over there.

I did the Barnett swap, and I don't have much seat time on them yet (damn winter), but they still seam to be fairly easy to pull in. (Maybe its because I'm used to 1000s)

If he put main jets in it, I sure hope not!

I had to change some things:

- Main jets: I was using 112 dynojet jets when the engine was 250cc. I change them for 120 but i didn't realice that they where Keihin. So, I have to change them again for 120 dynojet because it was runing lean.

- Transmision: had to change the 45 teeth sproket for one with 42. The acceleration was really good but the top speed was 175 kmh (110 miles). With the 42 sproket i reach 190 kmh (119 miles)

My clutch is starting to slip when the bike is not at working temperature, so I order kevlar discs, plates and stronger springs.

I'm really happy with the bike

Soon I´ll be doing a dyno run to see the final numbers

I'm using the OEM carbs with new jets. I would like to upgrade to injection but it's not cheap here

Well.. it's been like 4 month all ready and the bike is runing great.

I had a minor problem with the head gasket... a little pressure from the cylinders was going to the water circuit. I replace the gasket and use some copper gasket spray from loctite and so far I had no problem.

Finally I find a group of ninja 300 to test it out (all were std):

Sounds good, pulls redline in top gear. Was that 110MPH indicated?

Yes, about 13.500 rpm. Top speed was 118mph, I think that with another sproket it can reach 120, but for now I'll leave it like this.

Also I'm looking for better camshafts, did someone try others?
