Hi,my drouin is the 2 belt type it is very different on the bearing set up,it has 1 bearing in the impellor housing and 1 bearing in the outer drive belt housing cheers bazBruce Mac wrote:Hi,
The 40 MM Harley CV will not work well on the Drouin. I spent a couple of years screwing around with one before I went to the Lectron.
If you want your Norton to run like a Parade Float then use a Parade Float CV carb.
Also you don't need the ceramic bearings and most likely can not get them. Get the Barden bearings listed on Dyno Daves web site. I have been running the same ones since 2003 with no problem.
The most important thing you need to do is modify the bearing spacers to accept a spring washer as in the drawings to allow the bearing to move a little as the rotating assembly heats up and grows. I also suggest that after you do that , you get the assembly balanced. I recommend getting Total Seal rings to reduce blow by.
Belts from Belt corp. #400 panther 29 x 3/4" about $6.00 ea., one will last all season, Assuming you have a late model Drouin and the pulleys are aligned properly.
McMaster Carr belts will not work!
I frequently see 15 psi of boost on my stock 850, especially in 3 & 4 gear. Also expect your pipes to blue for about 20 inches.
I tend to ride more on my Ducati ST3S ABS more now, but the Norton with the Drouin is pretty close acceleration wise up to 100 mph.
Do it Right and you will enjoy it!
