keychange Posted March 5, 2012 Report Share Posted March 5, 2012 I have just replaced all the wiring (not the coils) on my Cota and it is running nicely again. However I have always felt that the throttle response is just too sharp off the bottom - just the slightest incorrect movement on the right hand brake can induce a dangerous spurt ( I notice some gloves are more prone to causing this). I have read elsewhere of people fitting a slow response throttle on their TLRs - I can state categorically that the response on my Cota is way - way more than on my TLR with a standard throttle. I have ridden to a couple of MrB's Bultaco's and the smoothness of the power delivery is very noticeable. Does anyone have experience with fitting a slow action throttle on a Cota and if so are there any traps with cables etc and will it improve things for me. I have found this unit for around 14 quids in UK and welcome feedback or suggestions Quote Link to comment Share on other sites More sharing options...
bullylover Posted March 5, 2012 Report Share Posted March 5, 2012 Hello Andrew, The Amal side pull throttles are very good but I think they only come in one speed. But you can get Venhil cables for a Montesa with Amal so you will have the best of both worlds. I have a Domino on my Sherpa at the moment only because I broke the Amal at the Aussie titles in 2010 and all I could buy on site was a Domino. They have two throttle tubes that you can buy. A slow and a faster one. They are also cheaper but require more fiddling to get the throttle cable to work. Standard Venhil anyway. The Tommaselli`s are also very good. They came standard on most Italian bikes in the eighties. You really have to buy Chinese to get an iffy one. Good luck and I hope we get to see you up in Queensland soon. Bultaco`s are always smooth, just ask Ross. Bully Lover. Quote Link to comment Share on other sites More sharing options...
keychange Posted March 6, 2012 Author Report Share Posted March 6, 2012 Looking at Amal T80/200 Throttle will it operate with the standard cable? Quote Link to comment Share on other sites More sharing options...
keychange Posted March 15, 2012 Author Report Share Posted March 15, 2012 Well in answer to my own question - NO - the existing cable doesn't fit - however pure dumb luck I bought a T80/200 cable for my TLR last month in error and sure enough it fits. However on a very quick wet ride - I can't really notice any change to the bike's pickup - yes the throttle is smoother and lighter but not sure the response is significantly different.

bullylover Posted March 15, 2012 Report Share Posted March 15, 2012 Hello Andrew. Have you thought of retarding the timing a bit to smooth it out. To do that you would make it spark a little bit closer to TDC. If the standard timing is 2.6 mm BTDC try it at 2.4 or 2.2 mm BTDC. This will smooth it out. Bully Lover.

keychange Posted March 16, 2012 Author Report Share Posted March 16, 2012 Yes Bully I was thinking that would need to be my next move - and it is a bit hard to start at the moment which suggests I might be a degree or two too advanced.
