Can anyone tell me the OD of a 4RT rear disc please, they seem to be half the price of a Gasser disc so i may fit one to my scorpa.

Several times today the revs suddenly dropped on my 4RT while I was sitting in a queue waiting to go in to a section. The bike seemed ok all the rest of the time but I've never noticed it before. Is it a symptom of something waiting to fail?

i was wondering if anyone could give me a ball park figure for a 99 and 01 315, the reason i ask is there is a 315 local to me but the bloke doesnt know much about them and was sold it as a 01 but it may be a 99 looking at the pics as it doesnt have the rainbow effect on the forks. its not on my door step so i cant just popover to check but he is keen to sell and it looks well whatever the year, few niggles with it but that is meant to be reflected in the price for a 01 but dont want to pay that for a 99 (or potentially older) model cheers

I've been contemplating installing a heavier flywheel! has anyone heard of a manufacturer that has made one yet ????..............................masso

I have bought a new mudguard and i'm wondering how to put the thing on!! are the rivets special? they seem to have a washer on them? Can anyone help me?

Thanks to all who helped with my last post. Can anyone tell me how much gear oil I should be putting in a 1982 Montesa Honda 123 and what 2 stroke mix ratio it runs on. many thabks Mike

How often do you open the air bleed screw in the left fork? and does the right fork have one ? or i need to open the top cap to vent the pressure.

The rear brake on my 02 gave up working at the last trial I rode and I've spent the last few weekends trying to sort it out but I seem to be losing the battle. I've put new pads in, given the calipers a good clean, bled new fluid through. Can't see any signs of leaks or bulges in pipes etc. When on the stand the pedal exerts enough pressure to stop you being able to turn the wheel but thats not enough to lock the wheel or come close to giving me confidence to actually ride the bike in anger! Any help would really be appreciated.

Although I dont own one (yet) I have always liked the Mont 315r and especially those funky green/purple forks. Anyway I noticed the new 4RT doesnt have them but has black forks instead yet (correct me if I am wrong) dont DL and Fuji still use the greeny purple ones?? Trivial I know but does anyone know why the production bikes stopped using them?

Keeping a clean airbox/carb! I use filter oil, grease around the the lip of the filter, grease even at the mouth of the airbox lid! But I continue to get dirt in the carb, I always check the boots between carb, cylinder and box to make sure seal is tight! Air box has no cracks seems good. I feel like I take all the proper steps in preparing a clean air flow on my 2003 Mont! How often do you guys replace your filters, buy new ones? sam

Does anybody know what the squish should be for a 315 (gap between top of piston and bottom of head at TDC)

Trying to get to the crankshaft seal. problems: im new and dont know alot. i have a gear in the way. probably dont have the right tool. solutions: i want to learn i have the time theres a small budget to work with. Are there any 311 familiar people that can help a tip on removing this gear to get to the oil seal. thankyou.

Can anyone tell me if it's possible to fit a rear brake caliper from a later model ('01 onwards) the style of caliper which is hidden behind the swing arm, to an earlier 315 (the one with the brake caliper sat higher than the swingarm. I know they both locate of a pin on the inside of the swingarm, just wondered if they are interchangeable.

Hi, Does anyone know what the ring gap is on the Montesa cota 200? Cheers, Paul

Morning, I’m looking for some help with my Montesa 301 RR 2022 clutch. I’ve had issues with the clutch since purchase a year ago. It’s progressively got worse with juddering, shrieking when hot and now a grinding sound under engine breaking. Ive changed the plates out for Mitani Alluminium discs, fresh HTX 740 and it hasn’t improved or changed at all. Any advice would be much appreciated.

I have an older 315 with the single pot caliper and paoli forks, will the twin pot ajp caliper fit my forks ?

Has anyone figured out which mini moto seat fits the 4rt nice yet ? You can save a lot going down this route ! The thumpstar seat works on the 2001 - 2009 sherco perfectly ?

Hi, Maybe a silly question, but is there an easy way to fit the return spring on the shaft, and into the locating hole? Cheers, Mark
