i loved the new clutch rides ......it works .... better ..... hey one more thing i can tell you is that the key will push that clutch out look at the crank shaft you will see how that would happin so i put my clutch on then i keyed... file the key way down if you are to tight with the key it will push that clutch out
hey can you tell me if the shift kit is worth it and did u get more top speed to me that motor mount looks better ..is it ohh i am hill less here

The 4 stroke shift kit is awsome well worth the money.I hit 38mph on one of those mobile police radar units and believe me it had more left to it but... I didn't!Scared myself.You have so many gear ratio options for the jack shaft and for the rear derailleur.You could climb a wall,go fast,or anything in between.

Well today was another frustrating morning trying to get the new replacment clutch to work with the Grubee III Gearbox. The shim I made was successful in keeping the clutch shoes and bell from binding on the crankcase and keeping the drive gear and the other gears properly aligned, but then when I closed up the gearbox and tighted the bolts the bolt on the end of the crank shaft was hitting the inside of the case (Photo #4) and making a heck of a racket. I filed a bit off the bolt and took out the lock washer and relied on just lock tight to keep the bolt in place. Closed things up again and part of the noise went away but there was still more noise than I thought was proper.

MasterLink when I tried installing the clutch as you suggest was successsful for you I wasn't able to line up the gears and would have never been able to get the two halves of the case to close up. I wonder why there is a difference.

As for your questions regarding the 4-stroke shift kit. I'm in agreement with MotoMagz, Its a great product. My top speeds aren't as high as MotoMagz (I've only seen 35 mph) But that was plenty fast for me. What I like most about the kit is with it you get up to speed much faster/quicker. With the gears the bike does not lug/bog when you start from a stop and at the top end the motor is not over reving. The gas mileage is wonderful (low to middle 170's mpg) and since you only have the one chain on the right side of your rear wheel when you get a flat it a really simple process to remove the wheel to fix the flat and get back on the road. I can't imagine you would be disappointed in the kit if you were to get one.

tap that clutch on with a hammer and 1/2 drive socket with out the key you will... see and hear it seat then you will be all done just the fact that you said the case almost closed ...let me guess there is a small mark where the bolt scored the cover ,,,,,,,this tells me its is 100% backwards ! i no this as i did the same dam thing .....here is my take on why this happins the old clutch makes the crank have a ring around the shaft ...at the back of the crank that doesn't let the clutch ride were it ment to

a different shim!!! maybe?

Would this work??? Might take several tries. Make a shim copy of the gasket that goes between the gear box and engine[the 4 bolt gear box mounting pattern] Maybe with the added thickness of the shim it might solve the problem

Well I finally got the stack height of the new clutch to fit inside the old type III gearbox, and got the cover closed and nothing rubbing/grinding the inside of the cover, last Friday. But the gear noise was just to great for me to put up with. It was worse than when the gearbox was brand new. At the time when I purchased the replacement clutch a friend purchased one of the 2009 5:1 4G Drives. He offered me the chance to try it out on my bike and I jumped at the chance. I installed it last weekend and though it's not perfect, I feel it is a vast Improvement over the Type III gearbox. It has some issues with the clutch engaging to early (at idle, worse than my old Type III clutch) but I think that I will be able to remedy this problem by either lightening the shoes or getting some stronger springs. So I'm giving up on my old Type III Gearbox and switching to the 4G for the Honda motor. Even the 5:1 reduction is not a problem since I'm using it with the SBP 4-stroke shift Kit. Its really easy and relatively inexpensive to change the drive ratios to a manageable range by changing chainrings and or the output driver on the jackshaft.

Well I tried to get a hold of Jeremy at Bicycle-engines.com to see what could be done about this clutch issue.Left him a voice mail (no response) and the kid I talked to on the phone was not very helpful.I just don't get how you can sell something that doesn't work???I have always gave them high marks at BE.com but not this time.I have had my stage II for 4 years with no problems until the clutch shoe went.The replacement bell and clutch was $40 or $50 shipped and RecumbentBill was selling the 4G for $80.Well sorry to ramble but I to am going with the 4G and the shiftkit.As ocscully said the shift kit parts are cheapto buy.I can't believ the ride is going to get even better!!!
