I am in the process of converting a Raptor 30 V1 to a 50 V2. I know I have to change the start bell, shaft, start nub and bearing. I went to the LHS and got the bearings that I needed for the upgrade, but when I put in the new upper bearing (PV0203)it is a smaller dia. outside so there is slop side to side in it. I had another lower bearing and it fits nice and snug. My question: Is this a problem using two lower bearings? They appear to line up perfectly, the frame has no spacing in it. Why would the V2 bearing not fit snuggly in a V1 frame? I am also going to put in a RL53. Is there any suprises I should know about?

Thanks for the info guys but that still does not answear my question about why the upper bearing does not fit snug but if I use two lower bearings (one in place of PV00203) it fits alot better

that is the right number for the bearings to fit the V2 starter shaft but it's been too long since I had my V1, can't remember if the OD of the starter shaft bearing is the same. I always left the V1 starter shaft/clutch stack in my V1, just had a V2 head and tail hub assembly.

You need to use the 16mm. OD. bearing on the top in the V1 frame. What you need to do is make sure the ID. of the top and clutch bell bearings are the same for your starter shaft, 5mm.(V1) or 6mm.

Are you trying to keep the V-1 frames with the V-2 clutch system? The V-2 top start shaft bearing outside diameter is smaller.You can apply 2 layers of shrink tubing around the V-2bearing and it will fitin the V-1 frames- I forget who came up with this fix but it works.

The V2

Has a larger start shaft I believe 4mm- so pinion bore ID. must match shaft OD.

Lower bearing must go over pinion - I believe is 6 mm. ID Hence the top bearing is 4mm I.D> and the bearing over the V2 pinion is 6mm.

Did mine - and I belive I had to get one of the bearings seperate.

I did a spread sheet V1 Vrs V2 with all the goodies lined up and you'll spot the odd bearing.

Clutch and bell bores are different also - Frame makes no difference.

OH the ol' shrink tube trick...man forgot about the uses of that. I was thinking of tape but thought that it would just spin after a day in the heat. Yep shrink tube is what I'll try. I'm changing out the start shaft assembly due to the larger clutch of the TT53. Thanks everyone....

Like greybird says you need the V-2 pinion also or drill out the V1 pinion you have now. The pinion is part of the clutch system (bell assy, pinion, clutch, start shaft, hex adaptor(you can drill it out too for the V-2 start shaft), and top bearing. Not really sure of all the stuff you have acquired for the swap.

Yep got a coversion kit from Heliproz and it came with a new pinion (10T) an a new main gear (85T) plus the other needed stuff. Didnt realize I had to change the start assembly until I tried to mount the engine...and then it was a total take down. So I just want to make sure of everthing before I have to take it apart again LOL. Good info guys
