Gday Mates, Hoping for a bit of advice on my situation. My 2006 Montesa 4rt has been at the Honda dealer for 9 months now. They replaced the cylinder head way back and since they are waiting on a final part (cover tappet). Simple part that covers the adjust holes. I call once a month maybe and they give the same answer. They have the part on order, but it's out of stock and nobody has a clue when it might be available. I'm wondering if they even make them anymore or how to find out. Any advice. I'm in the US and don't know too many riders. Does Honda make Montesa make parts anymore? THANK YOU!

I recently changed the oil on a 4rt (2006) and I just removed the two front bolts on the bash plate/skid plate/sump guard,....and left the bottom ones that get the abuse. This gave me space to do the oil change without the nightmare of putting the bottom plate back on 100%. Mine is pretty bashed up with no holes left for the allen wrench. BUT! Now the oil leaks like crazy when I ride. How do you guys seal up the side case after an oil change? Use a new gasket, yes. But maybe I need adhesive or ??? Please any advice on your process would help.

Quick twist throttle (the white one) on a 4 stroke bike. Easy change, BIG difference. I wonder if bikes typically come with slow or fast throttle tubes now days?

How can I liven up a dead rear end? ...that doesn't sound good (resist, as I'm doing right now, with dirty responses). My rear end suspension is too soft on my 06 Montesa 4rt. How much extra spring can you get from tightening the spanner nut? 2 turns? My hand adjuster knob makes no difference. I have yet to try the spanner as I can't find a tool to turn it. ALSO, I see a nip for adding nitrogen. Does anyone ever re-fill their nitrogen? Do bikes lose their nitrogen after time and is the result that it goes soft? I've never understood what a suspension "re-build" consists of. I'm new at this so thanks in advance.

Keep your front tire psi around 7 and the rear about 4 or 5. Soft is good but you don't want your front rim jamming into rocks. Quick Question: how much extra spring can you get from tightening up the suspension spanner nut on the rear? My hand adjuster makes no difference in softer or harder. I also see a nip for adding nitrogen. Do they lose their nitrogen after time (go too soft), and can it be re-filled?

Wow, thanks for all the help. I was mistaking 8mm heads for the thread size. So they're really 6mm bolts (sorry, I'm new at this). NEXT ISSUE !!! Now all my new oil leaked out after one ride. I can see exactly where too, around the electrical wire plug coming out of the case and up into..... SO, sealing gasket you ask? Yes, I put in a new sealing gasket on the left-side case after draining old oil. But was I supposed to use a certain adhesive on both sides of it? Manual does not explain that well...or at all. It makes good sense to do so but I was being careful not to use something that could seep into the oil, then your engine, etc. So I used a TINY bit of grease to make it stick a bit. (Same grease used on the air filter). It didn't seal things up enough and the oil is leaking faster than my adult diapers when I just don't feel like changing them after I've had a 6-pack of Tab soda. Main Q: How do you seal up the left-side after an oil change??????? THANKS - MontyTessy

Thanks for the info guys (or "mates"). The broken bolts are 8mm. Must have read the manual wrong to be at 16 pounds/sft. Also, the torque wrench was new and the cheapest I've seen in the states for $30 (normally $80+). Box says wrench is pre-calibrated.... but I'm not so sure now. I'll go soft on the torque. I don't know where to get "high tensile bolts" that match but I'll research it. I bought true Honda 8mm bolts after the first break, didn't help. I'm in the US where parts are rare.....this awesome sport is still in it's infancy here and I can't believe it!! I bought my sprockets on Ebay and the "nearest" location to buy from was the UK. Worked great though.

I'm new to trials and mechanics in general but enjoy learning on a 2006 4rt. After oil change, the bolts that secure the side cover on (about 6 or so) have to go on soooooo gently or "SNAP". I got a torque wrench and set it to 16 pounds/ sq. ft. as manual says.....and SNAP, again! I'm soiling my trousers over this! Not really. Is this an issue for anyone else? Do replacement bolts have to be purchased from Honda only? THANKS!!!!

I spoke to the trials mechanic here who said he'd change the springs in the front forks for $30 each plus cost of spring ( not sure what spring go for?). I wonder if that's a cheap and decent solution to the bottoming out I get when doing small jumps? The damper adjusting didn't help. still bottoms out. Back doesn't bottom. this bike has 4 to 5 years hard riding on it, so I've read about giving it a "re-charge". What exactly is done? I need to give the rear suspension some life back? Can the gas inside be re-pumped in or....? I adjusted the damper knob on the rear both ways and it's hard to tell a difference. THANKS for your help. Let me know what you've done to your suspension to make it better?

Thanks a lot for the replies. I think I was too anxious to get more rebound out of it and start hopping. I spoke to the trials mechanic here who said he'd change the springs in the front forks for $30 each plus cost of spring ( not sure what spring go for?). I wonder if that's a cheap and decent solution to the bottoming out I get when doing small jumps? The damper adjusting didn't help more than a tiny bit but still bottoms out. Back doesn't bottom. this bike has 4 to 5 years hard riding on it, so I see reccomendations above for a "re-charge". What exactly can be done to the rear suspension to give it some life back? Can the gas inside be re-pumped in or....? I adjusted the damper knob on the rear both ways and it's hard to tell a difference but it's made some. THANKS for your help.

I'm in the same balance boat. Just learned to keep it with wheel turned, and now working on straightening it out. Often we're getting the front wheel straight in order to prepare for the next obstacle. So I'm practicing coming out of the balanced position with wheel turned into a strait wheel.......and then getting my weight back and crouching down. After that, rev it and pop the clutch and spring up. I'm doing it on flat ground mostly and over small rocks. Seems like this will help in prep. for the bigger stuff. So, let out or whatever it takes to regain bal. is great I'm sure, as long as you can get into a position to move ahead or launch ahead after that. Cheers mate, Rick

good question. I'm not sure what function the bushings have. I take it from lack of response that it must be true, most riders ignore their suspension unless it leaks??? Seems strange when suspension is such a vital part of techinques. But I'm new so hey, maybe you just learn to ride what you have. I just watch these guys literally bounce around from front to back wheel hops or both wheels at the same time, and I know my bike isn't capable of that. So if anyone has experience in re-doing their suspension, let me know what kind of a difference it made? Thanks.

I"m brand new to trials and got a 2006 Montesa 4t. It was ridden pretty hard for 5 years before I bought it. I've noticed I have a lot of front fork bottom-out on small jumps. The rear seems really soft but not near as bad as front. Simple front tire bouncing takes a ton of knees and it barely moves. I see videos of so many riders who seems to flick the front tire around with easy hopping. I've tried all adjustments. Question is, how long does the suspension on a cota 4t last before springs are giving out and losing life? I had the fork oil changed recently by a tech and he said it hadn't ever been done. Does anyone know what it takes to "re-build" the front suspension? Cost and labor? Thanks very much for any input!!! Rick

My front fork adjusting knob (right side) broke off. The cost is about the same as new car to replace! I'm wondering if anyone has found a source for odd parts? They only sell an entire cartridge when all I need is the damper rod that extends the whole length of the right fork. Also, are Montesa's known for being soft on suspension? I couldn't seem to get any bounce out of if but might just be my lack of skill. Thanks mates

I've been riding trials for 2 months and don't have boots yet. I'm hoping they can help close the gap between the pegs and the foot-brake? I find it hard to "cover" the brake while riding without putting the peg on my heel (making me off balance). I have a 9.5 size shoe and ride a 2006 Montesa 4t. As I'm learning wheelies and after falling off the back twice, I'm learning to cover the brake! Do they make pegs that can set closer to the brake lever (this may throw off the balance) .....or is the brake lever adjustable? I checked it out but only found it to adjust up/down and not back or forward. Any advice is appreciated. Happy Splatters, Rick
