OSSA

I have a Tr300 that I just replaced the shift drum for and now I am having problems getting the engine back together. I have tried literally everything but the clutch fingers keep binding against the inside of the clutch cover and the kickstart will not engage or at least due to the engine being locked up. I have taken it apart and put back together about 20 times now and the main gear of the clutch is always flush against the primary gear on the crankshaft so I know that is not the issue. The tranission is also seated tightly against the engine and the secondary gear is at the right distance. I assembled my transmission drum based on this video but also noticed that the …

I keep hearing it spoken both ways, what one is correct?

What are the pros ans cons off buying a 2013 Ossa 290i Guy

Hi new to the site, but I have been snooping around here for a while. I'm interested in changing my bike. I have a 2013 Beta 300, but I just have no love for the bike, and feel it's time to move on. I have been looking at the OSSA and GasGas as the main choices. My questions, anyone coming from the Gasser to the Ossa find much of a differance? Plus I have a line on the 2014 for a great price, any major changes between it and the 2015 other than BNG? Thanks

My question is about the drive chain tensioner that pushes up on the chain and provides a tight wrap of the chain on the rear sprocket. The rubber pad that contacts the chain is attached to a steel lever that is somewhat spring loaded. There is an additional spring that attaches to the frame and goes down to the tensioner lever. This second spring was disconnected when I got this bike and the rubber has hardly any use at all. Should this second spring be connected by hooking to the bottom of the steel tensioner lever? If it should be attached, should I lube the rubber with, say, silicone spray? Thanks for any help on this. Jim

I want to lower the footpegs. The bottom of the pegs in the new position would be just above the skidpad level so the pegs will only be 1 1/2 or 2 inches lower. My question is about the affect this would have on operating the rear brake pedal. In the current position for the pegs, it seems like I am reaching down for the brake pedal but don't know if reaching up is good. Is there a way to modify the brake pedal. It is so well protected now. Any thoughts on this would be greatly appreciated.

Hi, my fan started sqeeking so I bought a replacement from Adrian @ Lewisport here in Ca. What is the best way to remove the fan? Fyi the fan is from Jitsie, fits 02-12 gasgas and jotagas 12-16 Thanks, Phil.

Anyone else had their coolant turn to a grey colour? Doesn't appear to have oil in it, and there is no water in the engine oil - its just gone grey and looks horrible. I don't know if its just broken down or if the stuff in the bike has been eating the alloy? We've flushed it out and put fresh (good quality) coolant in there today and I will change it again in a week to be sure all the bad stuff is flushed out. I've emailed a photo of the coolant to the importer. Also anyone know at what point in the delivery chain would the coolant be added to the bike?

I've made a new addition to my OSSA (2104 Explorer) The AAA Rechargeable batt (inside the factory Easystart) gave me some issues on a ride, so I hooked up LiPo battery and it worked great. But I didn't want to leave it in all the time, so I installed a KTM style start button. Wired it so the LiPo battery could apply power to the Diagnostics port. This runs the fuel pump for a moment and 'wakes up' the ECU. The bike starts first kick cold or hot. The LiPo battery is quite small. I'll get some pics etc. working on getting more connectors, but just used the 'dummy' plug with some appropriate pins. Mark

Anyone having/had a problem with there rear brake pedal ? mines been sticking on every now and then and i have pinned it down to the ball joint pin coming loose from the pedal which is allowing it to twist and catch on the frame which stops the brake from coming off fully jsp

Yesterday I had a strange incident while doing a rough track - rear brake got locked up. The disc and the saddle was overheated (it smoked), brake pedal was completely locked and unmovable. Needed some 5-10 minutes to cool down and then worked fine again, pedal started to move and brakes worked again. There were no leaks. Anyone else had this? Oil seems to be quite dark from the master cylinder inspection window. I wonder if I need to overhaul the master cylinder and the caliper hydraulics or just suffice with replacing the DOT4 oil for now?

Anyone seen any after market 2012 280i rear hubs ??? snapped a disk lug off today so need a new one and would prefer to get a bling coloured one rather than a std Ossa one. If anyone has any idea please post up. Cheers in advance.

anyone got any of these kicking about or where to get some from, I have found them somewhere but at £8.38 each I think there a bit steep, I only want the square nut if anyone no's what the technical term for them would be.

Just a curious question regarding shock mounting point size, I have just got hold of this project and just going over it to see what's what, and noticed the hangers for the shocks are quite big 15mm it's been powder coated by previous owner and looks like a collar has been left on all the mounts? Can anyone tell me what size they should be before curiosity gets the better of me

Hi there, Anyone know where i can get a spanner to adjust the spring on the rear shock. Don't like the idea of using a hammer and screwdriver or a hammer and a piece of wood! I find the rear shock really softens up too quick. I am not heavy <75 kg but find it bottoms out way too easy! Thanks

Anyone changed the rear sprocket ? I have been told that aftermarket 4 bolt sprockets need some sort of machining to fit ? what needs to be done ? Also anyone know if a 44 rear sprocket will fit onto a std chain ?

Hi Guys What are the torque settings for the rear sprocket on a 1976 OSSA MAR?

last sunday the main shaft in my tr280i suspension gave up the ghost which then snapped both my linkage arms. after a quick strip down sunday night i rang Ossa UK monday am to be told no problem post the broken parts to you dealer and we will supply the new 2013 kit which is a lot stronger. weds am all the parts came so a big thank you to Ian at trials & tribulations and Nigel Birkett at Ossa UK for excellent customer service. jsp

Ok, I broke one of the 'Dogbones' in my rear linkage. It is the new type with a bolt. After a lot of thinking, it probably was my fault. I think when I lubed it last time there was still silicone grease in the threads. So the locktite couldn't hold- the bolt backed out and must have jammed against the swingarm, breaking the shaft. The too much for one side still left when I hopped over something. Anyway, the dealer ordered the part, but OSSA sent the wrong one! There appears to be a mixup with the part numbers in the manual. So...does anyone know where one may be? They are going to try and get one, but I'm looking also. Please let me know. Mark

Hi, I am looking to get a spare rear wheel for practice but haven't seen much online. I have seen gas gas, beta, etc and was wondering if anyone knew if any of these other wheels would do the job? Thanks in advance...
