swooshdave Posted February 28, 2008 Report Share Posted February 28, 2008 I have seen an adaptor to fit the WES exhaust to the stock pipe. Quote Link to comment Share on other sites More sharing options...
scottt Posted February 28, 2008 Report Share Posted February 28, 2008 There was a TY175 restoration faetured in the first few issues of Classic Dirt Bike, the guy there fitted a new front pipe and a new middle box the problem was that the front pipe is smaller so it fits inside the original box and the new middle box has a slightly larger diameter as its designed to fit over the original front pipe, the result is that using 2 new parts results in a gap that requires a spacer as its impossible to clamp them together without there being a gap.

andy.t Posted March 2, 2008 Report Share Posted March 2, 2008 Dont know if anyone is interested but I contacted Craig with regards to the mentioned Exhausts that he has for sale(the Quote Link to comment Share on other sites More sharing options...
majesty320 Posted March 3, 2008 Report Share Posted March 3, 2008 WES do a two piece system for the TY175 it is the one shown on John Wilkinsons bike in classic dirt bike magzine. The spacer he talks about is needed because the WES system was made to fit the origional TY front pipe not a Miller front pipe, which has a slightly smaller diameter. If you need to know more about the system John Cain at Trail & Trials UK sells them. Just type tytrials into a search engine and it will give you his web site.

majesty320 Posted March 5, 2008 Report Share Posted March 5, 2008 Thats because the ones Craig Mawlam sells are WES middle and tail pipes.

majesty320 Posted March 5, 2008 Report Share Posted March 5, 2008 Sorry I forgot to add that the front pipe craig sells is not from WES Quote Link to comment Share on other sites More sharing options...

majesty320 Posted March 6, 2008 Report Share Posted March 6, 2008 (edited) Dont know profit margins maybe. I believe he gets them from Snezzy Yamaha in Holland or Belgium, who get them from WES. But they are definatley the same make. He told me so himself. Edited March 6, 2008 by majesty320 Quote Link to comment Share on other sites More sharing options...
mollygreen Posted March 7, 2008 Report Share Posted March 7, 2008 (edited) The Miller rear silencer (probably WES also) No it isn't! The question of WES exhausts and SM front pipes came up before in July last year and I have copied in the piece I wrote for you all to enjoy again. I have a Sammy Miller front pipe linked into a WES two piece mid section/silencer system. Even though I live 5 miles from S/M's shop, I had to buy it from JK Hirst's as Sam didn't have any in stock, but that was OK as I had bought the WES from JKH also. (very good service). The front pipe that they supplied is an S/M one. As to the diametre of this pipe, if is is smaller than the original, it aint much and I haven't found that it chocked the bike, on the contrary, having a complete new exhaust has made my bike run bloody lovely. There is a difference of about 2mm in diametre between the front pipe (40mm O/D) and the WES middle section (42 I/D) and to get over this, I used a piece of 0.8mm thick gasket sheet rolled up in between the two pipes, stuck in with heat resistant silicone sealer and used a good quality strong exhaust clamp that I bought of off Ebay (I could have bought one from one of the stalls at Motorcycle World, but it was too late by then) and clamped the whole lot together, and it's great, I'am well pleased. One word of warning though, the WES exhaust has no guard and does get f*uckin' hot and burns your leg if you aint careful while riding! One last thing I felt needed to be done to the front pipe was to grind out the most horrible looking miss-match of the tubes that are thankfully accessible because they are at the exhaust port end. This is where a curved tube is welded into tube straight tube with the flange on it and the bit inside needs to be ground away to encourage a better gas flow. You can't get it all out completely smooth but I have made it a million times better and having spent the last 27 years in engineering, I couldn't bare to leave it like it was.

I know what you mean - the 250 pipe is horrific as well. Couldn't quite believe it when I got it that someone would sell something so poorly finished.

Couldn't quite believe it when I got it that someone would sell something so poorly finished. Woody. I take it from this that you have one also. Did you grind out the inside to improve the finish? As previously said, I have worked in Engineering for many years, a lot of which was working for a company sub-contracting into the aircraft industry and specialising in double curvature sheetmetal and pipework. So I should know how it's done properly. Some of the work I used to do involved multi bend 1 3/4 o.d, thin wall stainless tubing that went somewhere on the environmental control system of an aircraft and was manufactured to a tolerance of 0.005th of an inch between the flanged ends with smooth inner joints for unrestricted air flow. Now I am not suggesting that an exhaust front pipe needs to be manufactured to that standard (outside of WSB or Moto GP that is) as the costs would be prohibitive but, it was very dis-heartening to think that manufactures are selling these front pipes (which are supposed to be an improvement on the original) with this amount of airflow distroying internal overlap. It is just a case of better tooling and more importantly and improved mindset as to what you are trying to achieve when manufacturing these after market products. Exactly the same can be said about the SM footrest lowering kit that I also have on my TY250. (But that's another story, neadless to say I am making my own improved version) A word of advise to anyone thinking of buying an SM front pipe, be prepared to do some work on it before you fit it, otherwise it may prove to a disapointing waste of money. On the other hand, I have seen pictures of Craig Mawlem's Majesty front pipe and they look well made. Does anyone have one? Are they as good as they look for fit, internal joint mismatch etc? and would they fit the standard TY250? I know that Craig is aware of what is being written on this site, so I would be interested to know! Quote Link to comment Share on other sites More sharing options...
