  1. Cheers guys... Assumed this would come down to discipline... Never a good point for me as I generally try not to wake up until half way round the first lap.. Must try harder.

    Gro Oil

    So, I bought some GRO Oil in the Summer and have finally run out of what I was using before... As best I can see GRO is colourless and odourless... So, once I've mixed it into one of my two identical jerry cans, its impossible for me to determine which one is pre-mixed and which is just petrol... Previously (with Putolene), I could just pour a little into a mixing pot and see the blue colour from the oil. Anyone else have this problem? Aside from the obvious of being disciplined and marking the jerry cans etc, I wondered if there were anything I could do to the oil (something simple like food colouring) that will make it detectable without destroying my bike? It seems a shame to just not use it and I'm sure I can't be the only one with the problem? Ta.
  3. I had the same thing last year.... I actually had two problems, so I'm not certain which one fixed the problem. I was leaking fluid from the overflow pipe, but it wasn't clear if this was spitting because the bike was getting hot. I notice the fan was intermitent. It would start up, but cut out from time to time... I also notice it would speed up and slow down based on engine speed (revs)... I replaced the rectifier and this seemed to go away. I also noticed a hairline crack in my radiator which could have prevented the radiator holding pressure... hence boiling over and spuffing out of the over flow. So I also replaced the rad. I woudl recommend testing the fan with a 12v supply as others have mentioned, then definitely try the rectifier before you start spending mega bucks! Good luck
  4. Hi all, I'm in the market for an upgrade to my 2000 TXT 250 and have been looking at 2010 (maybe 2011) Gas Gas's as well as Evo's and Sherco's... As I'm a bit of a porker (16St) interested to know whethere after market heavy springs are available for the Gas Gas. I was sold a heavier rear spring from an Evo on the understanding that it would be ok on my current bike. Whilst it does fit, its not perfect. It is really tight with the airbox etc. So, is there somewhere I can buy these bits, before I commit to sticking with Gas Gas. p.s No, I do not want to join the gym instead... ha ha Thanks in advance. Dave
  5. Hi mate, I do a fair bit of time at Poles Wood as well. It's been a few weeks as there's been a few local trials on, but it's a bit quiet again now through to Feb, so I suspect I'll see you over there. Sundays seems to be the busier day if you like riding with lots of people.. I'll be the one wobbling about on an old 250 Gas Gas (Blue) . come and say hello Dave
  6. This is where most of the owners manuals can be found http://www.trialspartsusa.com/tech.html But, looking on 2001, it doesn't mention a 50? Scan through the site, its your best chance of finding something. Hope this helps Dave
  7. Just a thought, but are there any garages to rent in your area? I live outside London, but I have hired two different garages in my area, generally in blocks behind flats. I've paid about
  8. A little update... The bike is now rebuild and sounding much better. There was / is some minor complication which is causing teh bike to over run slightly when revved. a "man in the know" had a fiddle with the carb and it got a lot better. I'm planning to check out the jets at some point to see if I can't get it perfect. But, the bottom line is, it is now mobile again and got me through the trial at Danbury on Sunday. Good times. I did however try to blame "running the engine in" for me fiving a section... truth is, I was just being a pussy with the throttle! ha ha
  9. On the understanding that I dont easily have access to the technical equipment to make those assessments, I took it down the shop and let them have a look... I'm assured the wear is over the top and so its been sent off to be nikosil'd and I've got a new piston on the way. I 100% can't afford that, but nevermind. I've also asked for gaskets, o rings and little end bearings. May as well? In terms of the airbox issues (good memory by the way JSE), I feel fairly happy those are now resolved. I've put the bike through some fairly unpleasant conditions and there isn't any evidence of filth getting past the filter or any obscure openings in the rubber / plastic. Before long I will have replaced almost everythying on the bike! I can lay claim to owning the newest old bike in the country!
  10. The connecting rod has a very small amount of play side to side. The movement I'm talking about is the piston moving along the small end bearing. I'm fairly sure this is normal. I looked at a parts drawing and it shows the small end bearing is considerably wider than the small end of the con rod. I kind of assumed that there should be some packers or something to limit this movement, but the drawing confirms that what i have is normal. In terms of signs of abuse, I really can't see any. There are no marks, scrapes or signs of deformed amterial inside the bore or on the piston. Howver, if I grab the con rod in one hand and rock the piston side to side, there is slight play which makes me think its just the little end bearings? Given that the little end bearings for my bike are less than £20, I'm inclined to replace it, rebuild the bike and see if theres an improvement? £20 and an hours work to rebuild seems like a risk worth taking if it means I save £350 for new pistons and nickosealing. I'll also try and measure the gaps around the piston inside the bore. Can anyone tell me what to expect? I'm pressuming a set of feeler gauges for setting spark plugs should be ok? Cheers, Dave
  11. Hi Phil, There is a manual for the front suspension, but I can't see one for the bike overall.. click here for the forks manual. It may help a little. Other than that, I'm sure someone on here can offer some wise words.
  12. its a rattle. It really does sound like a diesel. The gas gas dealer who listened to it said piston slap and a few others have said little end. I have no idea
  13. Hmmm...not quite. I've taken the barrel off and the so now the piston is exposed and fixed to the con rod. The float is along the little end bearing I guess?
  14. Hi (again) Ok, having rebuilt the bike after the last bout of issues (broken kickstart gear, sticking throttle, cracked airbox.... etc) I rode at a trial and was told by a few knowing souls that the top end has gone. I'll not bother trying to explain the noise it makes, but it does definitely run with a rattle which has attracted remarks about the it being the new Gas Gas Diesel... blah blah blah. Anyway, I took it over to someone in the know and was told the noise is piston slap and that I should strip off the head and piston and send the head for nickosealing. So, obedient as I am, I've stripped the head off this evening and I can't see anything wrong? Having been around when someone bravely dismantled their bike in the woods for the same problem, the head was passed about and everyone was making comments like "jeez, its mullered", "look at the state of that" etc. I never looked at it, but I assume it has to be pretty bad to be so obvious? So, before I rush the parts down to my parts man what else should I be looking at? The piston has side to side movement of about an inch, but it feels like the sort of movement its meant to have. Its slides rather than slops. If I grab hold of the con rod and give it a wiggle there is teeny tiny bit of play as it disappears into the crank. Finally, if it is decided i need all the new bits, how do i get the piston off? I can see some sort of clip, but can fathom how to remove it and I've learned my lesson with just bashing stuff now! Any and all help would be great;ey appreciated Dave
  15. hi David, I'm glad you're enjoying reading my thread... I'm enjoying writing it, despite my constant bleating of misery! ha ha... I have certainly learned the lesson of expensive hobbies... But, that said I think even I wasn't naive enough to think I'd get away with a tenner in the honesty box every week and just ride forever without any expenses... I just hadn't quite thought they would be as expensive and as frequent! Still, my philosophy is "in for a penny in for a pound"... If I stop now, I've achieved nothing. I've not got an operational bike and I've got not really got anything worth selling, so I shall plough onwards. Eventually I've got to have fixed everything right? ..... right? ! ! With the "knocking", my ear isn't sophisticated enough to know what it is, but two seperate people telling me exactly the same thing is enough of an indication. I spoke yesterday with the guy that will get the parts and he assured me I should be ok to ride it a few more times without too risk of implossion or instant death, so I'll ride it in the local trial this Saturday, then hang on to it for the bank holiday weekend, then strip it down. I'll buy a kit of parts to replace the small end bearings etc anyway. If, when the barrel comes off, it looks ok then I'll simply replace the worn parts and be on my way... If not, off it goes to the shop for nickosealing. Referring to your comments on the chain, I am certainly no pro and not really capable of a great deal of hopping either! But, it could be worth looking at. It may be something to go on the back burner, just in case I ever experience a month where I haven't spent over
