TYRE CHOICE

[MGI]

The saga continues, should be sorted tomorrow, but in the interim period does anyone have any advice re the drum bearing retaining clip? as mentioned it is about an eighth shorter than the groove it fits into and one end of it has a hook like projection which will not fit into the groove being slightly bent out, the other end does fit snugly into the groove and is plain!

I bought a bike, not a BSA, and it had fitted modern tubeless tyres for spoked rims. I was a bit worried about these as initailly the bike handled very differently to, a similar one with traditional tyres. Then I blew these up to 40psi and they are great, and the back one very round.

Have a look at Central Wheel

been using Heidenau tyres on my bikes for years and very happy with them (B31, B33, M21, G80S, TR6).

I have a 350/19 Avon roadrider on the back and the same on the front although the front should be a 325. The front literally just fits between the mudguard stays. The local dealer advised thus. Due to inclement weather (I only fitted the front yesterday) I have not had a chance to try them out as yet. When I removed the rear wheel I also replaced the original (as fitted when I purchased the bike) drum & sprocket for one with less teeth, 42 instead of 47. I think the original was an A65 type with the sprocket bolted onto the drum whereas I now have a drum with integral teeth. This was rendered necessary because the engine sprocket was changed when the starter was installed resulting in a somewhat under geared situation. I haven't really tried out the new combination yet but I do know that it still starts off OK and doesn't feel over geared although I only rode it up and down the road just to check as I was slightly concerned. The saga experienced during the drum change over was unbelievable, even the chain shortening was a disaster, it is all down to experience and I won't bore you with the sordid details but the time taken was measured in days!
