Thanks a million! I like your plan of action! I was concerned that the Malossi gears were proprietary to Malossi and wouldn't work or mesh properly with other manufactures gears. If the straight cut gear profiles have all been standardized, then I have a viable option!
I also like the idea of removing the case rib now incase I need the bigger clutch. The time to remove the rib is now while the engine is on the bench. I can position the engine as shown in the picture which cause the filings to fall to the bottom.
I also like the idea of riding the scoot with the current set up and see if a clutch cog change may be needed!
That Dirko video is great! That stuff really flows well! A little goes a long way.
How much Horse Power do you estimate the engine will make? Keep in mind no case machining is being done.
Estimating horsepower is really hard without some serious software. That being said, I'm going to do it anyway and guess you'll get 13 HP, a little more than a stock P200. The difference is that you don't have the low end power band that the P200 does, which is why I'm worried about your gearing.
Since you're going to be upgrading the clutch sooner than later anyway, I agree that you should get it running, see what you think of the current gearing with the six spring, and then make a decision.
And, yes, that's the correct tab. I did my in the bike and used a pair of vice grips. I put the 7-spring on and marked where to break it off. scored it, and it snapped off cleanly on my SprintV motor and the vice grips caught the piece. All good
