gud2bridin Posted December 17, 2012 Report Share Posted December 17, 2012 Hi, I have just bought a Beta Techno Dougie Lampkin Replica and am putting a new chain and sprockets on it. Can anyone tell me what is the correct no of links to shorten the new chain to as it it currently far too long. i was going to move the rear wheel forward as far as will go then shorten the chain to suit this. Is that correct? Thanks Quote Link to comment Share on other sites More sharing options...

2stroke4stroke Posted December 17, 2012 Report Share Posted December 17, 2012 Generally you want to run with the shortest wheelbase you can so what you propose is correct. You may even be able to use a half link to get the wheel further forward. Quote Link to comment Share on other sites More sharing options...
gud2bridin Posted December 18, 2012 Author Report Share Posted December 18, 2012 hi, thanks 2t4t, did exactly that and seems fine. The cams are about 6 notches back. Cheers Quote Link to comment Share on other sites More sharing options...
b40rt Posted December 18, 2012 Report Share Posted December 18, 2012 You should also check that when the suspension compresses that the chain doesn't become to tight, bad for your new chain, worse for your gearbox. Quote Link to comment Share on other sites More sharing options...
