    Well the best thing to do is to check to ensure that the thermostat is working correctly. You can remove it and place it into a sauce pan and check to see if it correctly opens at the right temperature when left to boil. If your daily commuting the bike, then leaving the thermostat in is advisable. Yamaha know what they're doing. If you start tuning the bike and pushing it beyond its original specifications, then you may want to consider removing it. The thermostat isn't just there to aid heating up of the engine, it also has a role in providing pressure in the cylinder head to avoid pocket stagnation of gases. So it's actually important it's fitted. I just noted that these engines do run warm and removing the thermostat allowed my bike to run at a more consistent temperature when under load.

    I'm not familiar with the market, but a cylinder piston combo with all the work ready to go has got to be £300+. Any more than that then I wouldn't understand why someone wouldn't go for a brand new Athena 125 kit, or a little extra for the 170 kit. The Zeeltronic, new they're around £240, so with the programmer I'd say £160ish is what I'd pay, otherwise I'd just go new. Hope that helps.

    @Stevie-Wonder Thanks bud Greta (for that is her name as she's noisy, irritating, aimed squarely at the youth market and responsible for thousands of them bunking off school all over the world) cost me half as much as my '93 due to the mileage and had a thick layer of grime all over due to years of grinding commuting. I gave her a scrub with Jizer (several times) and this is what was underneath Here are the part #s for the toolbox and lid, bit pricey IMO and you'd have to get the lugs welded on to a non-e start frame. Be a nice touch if you were getting it powdercoated sometime though https://www.cmsnl.com/products/boxtool_55v2817301/ https://www.cmsnl.com/products/lid_55v2818500/

    As Calum said, you'll have to Jet it accordingly to try and get the best amount of mixture possible. But in my opinion it really just depends how much time you're willing to perfect it. If it's just something you want to thrash and aren't worried about the results you can probably skip a couple steps... I've certainly done that.

    In the 3 years I owned my Gas Gas trials I never had a problem, changed the clutch and piston due to my riding style being heavy on clutches. Parts were easy to find and reasonably priced in my eyes, and it was just fantastically built and designed. To this day my favorite bike ive had, really regret the sale.

    Michellin AC 10s if you want to do some proper technical stuff, if you just want dualsport tyres which are good both on and offroad I use some cheap vee rubber ones that came on my WR wheels during the summer, gripped well offroad in the dry ish mud and I hit some gnarly stuff, utterly useless in bogs or bad mud mind, as are all dualsports.

    @natnice Standard size tyres are 80/90/21 front and 110/80/18 rear, You can fit 90/90/21 and 120/80/18 on the stock rims, but if you want wider tyres than that, you will have to fit wider rims first bud.

    @oldman said in White: Have managed to find white panels, new and original, for the 89 when I start. Received a new panel today and it's off colour compared to the others, are there variations in shades/years?[image: tB0uqCY.jpg] You have the part number off the bag they come in for the side panel

    @andrewj1680 said in Hello All: My rgv250 was a animal i find hard to believe a rs125 would come anywhere close to it I've owned TL1000S, 996, Tuono 1000 etc so I know what animal bikes are like to ride RS125 was just a really nice small capacity sportsbike that's what I was getting at. Obviously an RGV will be quicker, but sometimes there's more fun in maxing a tiddler
