Ham2 You say your bike is to soft, if this is the case I'm guessing it's probably getting ready for a new set of rings and maybe a piston as well, by all means try removing the spacer first but I guessing you will hardly notice the difference. Same goes for the short header pipe and keihin carb, these will make a lot of difference but not what I think you are after, more bottom end grunt, the longer header pipe on the 05 bike was done to help the bottom end so putting a shorter one on won't help and the keihin carb yes it does make a big difference but most people comment on now it smoothes the bottom end out, if anything it losses some bottom end grunt. Chris

Hi I presume you mean the spacer in front of the reed block, if so it moves the reeds and carb further away from the engine decreasing the crankcase pressure softening the bottom end and making the bike slightly less responsive as the carb is slightly further away. Sherco put them on in 2005 but then this year bike dosen't use one but the porting on the new engine is totaly different. You can take them out it won't do the bike any harm as long as you put a new gasket back on and make sure it seals perfectly, a leak down test will make sure. Personaly I wouldn't bother, it's fine with it in. Chris

into the barrel

Malcolm Rathmell Sport will sell you a new Olle or Sachs shock absorber but neither have damping adjustment. Tel:01423 772885 The Olle shock you mentioned looks like the standard sherco shock from the earlier bikes (1999-2003 ish) and if it is this also has no damping adjustment, it says it adjustable but I'm guessing that it means the preload is adjustable. Your 2004 bike came with a sachs shock so I wouldn't recommed buying a olle shock from the earlier bikes, they usually change things for the better. This years bike has gone back to a Olle shock but a totally new design though.

What do you mean by it feels cold on low revs, I don't understand. If you mean it lost some of it low end power then thats probably normal as your putting a larger carb on. What jets are you using? More info required.

Next time you silicone it up try wraping one of the bits with cling flim then this bit can be removed after the silicone has set leaving a nice mould of the part so when you put it back it shouldn't need resealing.

Sherco don't give out info like that about their bikes. I'm only guessing here but I doubt there would have be any real difference in peak power between a 2001 & 2005 125 sherco, on the other hand a well used 4 year old bike will probably be quite a bit down on power compared to a new bike. If you want lots of power put a 125 motocross/road race engine in your bike and watch your results plummet as you'll spin when on the power band and stall it when you're not on the power. What you really want is torque at low rpm's and a nice smooth power delivery, sherco have improve the 290 in this area for 2005 and presumably they have made similar improvements to the 125 but I can't really say as I haven't ridden them both. Cheers Chris

Hi Here is there website but it doesn't appear to working at the moment. http://www.malcolmrathmellsport.com/ Tel: 01423 772885 Cheers Chris

Yeah it was me who was selling it and my brother has bought it seeing as it was so cheap. I'm a bit disappointed really expected it to go up a lot more than that, I've sold my last 2 bikes on ebay and got good prices for them, must have put it on at the wrong time or something. I'm quite shocked at the price of that Montesa especially as there is no picture of the current condition only the condition when new.

Are you joking or is this a serious proposition, haven't the over 40s got there own championship in the classic rounds. I haven't got a problem with this but most novogar rounds are way to hard for most over 40s if they did this surely they will have to go to two routes. I know John dislikes the idea of two routes mainly I think because the section are laid out for the hard route and the support class end up going around everything. He also say riders such as Dan Thorpe, Tom Sagar and myself have or own championship which is true but this is run on two routes so we have to suffer riding the support class going around everything in that. The general consensus is that the Expert Championship works well so why can't the novogar also work well under two routes. In my opinion I would like to see the novogar stay at a similar severity but with a clubman route, this would probably only need to be used on half maybe a quarter of the sections and have the rest the same for both routes. Also I don't really see the need to lessen the no. of rounds simply reducing the number of round that count would help more oh and not having them clash with British Championship dates would help. Cheers Chris

They are the right kind of tool but tend to be to wide for rear shocks I sure you will find something if you search for C spanner on google.

The plastics are cheap ish, the stickers, rear light cover ect that add to the cost. Ring Malcolm Rathmel Sport up they will give a price and send you them through the post. Tel: 01423 772885 Oh the 05 plastics will fit.

Did you ride Psycho? What did you think?

The divider plate as shown in this link http://scaryfastracing.net/pnp-info.html

No problem

Webmonkey We've got another trial on this sunday if your scoring system is ready for testing. Cheers Chris

Have you tried it then the venturi diverter that is, if so are the claims reasonable. I'm using a 28mm keihin pwk at the moment so the bit of blockage may not cause a problem, only one way to find out I suppose.

Here is the pic, I hope you dont mind trialsurfer. Looks like it will help with the air flow and maybe add to the venturi effect, in standard form there is a lot of little restrictions to the air flow which can't do it any good. I guessing you have to use smaller pilot jet after you have done this mod. Have you ever thought of trying this kind of thing out http://scaryfastracing.net/pnp-info.html I might try it one day see what difference it makes if any. Chris

Well done Gill and Robin Tut tut Mr Thorpe should have had Colley after such a good first day

I take it your not allowed a bigger bike been a lad. Where do you want more power on the top end or all the way through the rev range? How old is your bike, well more importantly how much use has it had? If you want more power a new piston and rings may help more than you think. Does your bike run sweetly and rev out, if it isnt reving out you may have a blocked up exhaust or the carb jeting may be incorect either of these will lose you a lot of power. Putting a larger carb on may give you a little more power by letting the bike rev higher but it will probaly lose lowdown torque which is what you use the most in trials. Cheers Chris

Yes it will just You have to strech the rubbers a bit to get it to fit and the trottle cable is sligthly to long but you should be abel to cut the top off cable bend bit that goes into the top of the carb with the adjuster on it. Just wondering why do you want to put a bigger carb on a small bike?

They are changing the whole range.

Webmonkey I know it probably to short notice but if you still want me to try your scoring system I will quite happly try it out tomorrow after our trial. Cheers Chris

Altho the cases are similer to look at they are different so new tooling would have been needed anyway.
