[Resumed thread on Start Motor Clutch topic]
I would like to be there, is the club getting a stand and tickets ?
http://www.donington-park.co.uk/events/motorcycle/donington-classic-motorcycle-festival/10058/#event
Yes we have an invite, parade lap (?) places and our super slick new Gazebo on show this year.. Looking forward to it..
Fantastic !! Do you want my bike on the stand Glenn or do you have enough?
Hi Gareth – it would be good to have it on the stand as you are going to be there in any case… it’s an RD I think…?
Yes Glenn it is an RD and it will be in race trim with most of the shiny, glassy bits taken off for Spa. Having said that the starter clutch has failed, and the LHS of the bike is in bits as I try to rebuild / replace / modify the sprag clutch. Grrrrr!
Hi Gareth, there is a solution for the R starter clutch problem, and that is to use a 1999-2001 Yamaha R6 5EB sprag, you will need a cb750/cb900f starter clutch hub and starter gear
As you can see from the photo the R6 sprag has around 20 teeth to grip rather than 3 rollers, and you use 6 bolts to secure it
I have been using this mod on my CB1100F Hondas (2) for 3 years now with no problems, always grips never slips
If you send me your email i will forward you a word document with full details

Keith,
I think might be a market for you here, selling a complete modified sprag clutch ready to fit on !
Put me down for the first one please.

Steveb:DThis would make a good piece for the club mag too Keith..
Please forward to me or Andy Larkin if you’re happy to let us use it. 😃I have already sent Andy the word document a couple of months ago Glenn

It’s a well known problem of course, but we don’t pay much mind to is until the bloody starter clutch goes. In my case at the worst possible times. I’ve had two go now in the past 2 years and I’m out of spares
so will be looking at this Yamaha conversion. Seems the priciest item is the Yam Sprag itself.
