Definitely ALLAN

I returned to Trials last year after 30 years away. My last bike being an ex-works Comerfords Bultaco 350. My first bike back was a 2007 Sherco 290 followed by a 2008 Scorpa 250 (flat as the proverbial) a 2013 GG 250, a 2013 Jotagas 300 (loved it but keeps breaking the gear selector shaft), a 2009 GG 300 Raga (loved it but needed too much doing to it) and finally a 2016 Sherco 300 which I absolutely love. Some buy a 300 and then put a slow throttle on and a flywheel weight to calm things down. Myself, It took one easy trial to bed myself in to the throttle response and it is now perfect for me. BTW, I am 73 this year.

Great Video.

I certainly would. In fact I ride a Jotagas 300 which is the BEST modern bike I have ridden so far.

Sod's Law. I was just reading that this morning.

Forgot about Lincoln Club http://website.lineone.net/~lincolnmotorsport/

Haven Trialsport run a practice ground in a Wood at Hatcliffe https://www.facebook.com/haven.trialsport/?fref=ts Trials park/zone up here in North East Lincolnshire will be open all over the christmas period and unlike last winter, you can drive in and park up now without getting muddy tyres! £15 per day or £150/200 for the year (phone 01472 236117) And we have toilet facilities (no central heating though!)

North Lincs Pre-65 & Twin shocks but they allow modern bikes with no championship points. Run some GOOD trials https://www.facebook.com/northlincsclassicmotorcycleclub/?fref=ts Scunthorpe Club run trials around Lincolshire https://www.facebook.com/scun.mcc?fref=ts

Lipos lose voltage when cold. So do NOT charge cold and take them into a warm room/car/van. Use a storage charge when storing and check the voltage on a regular basis. If the cells drop too low, they may be damaged and fail to charge,

I have used Lipos for Radio Control Helicopters & Aeroplanes for several years. The ONLY batteries I have had that have gone up in flames have been due to a CRASH. What charger do you use? I use a Revolextric Charger and charging and discharging balances all my 3 & 6 cell Lipos. I always charge at 1 C. This means if I were charging your 10C Lipos it would be 8 amps at 1C. The other thing that has an effect on Lipos is the Discharge rate ie. C rating. The Lipos you linked are 10C rating which isn't very much. I use 35/40 C on my Helicopters and 20/25 C on my Aeroplanes, But of course it depends on the Motor power drawing current from the batteries. I also use a Parallel Charging board which helps to balance all the cells in all the Lipos I charge at the same time:- http://www.hobbyking.com/hobbyking/store/__28273__Hobbyking_Parallel_Charge_Board_For_6_Packs_2_6S_EC5_.html

Hi Roger. I have just come back to Trials after a 30 year absence from bikes altogether. Quite a few clubs run Learner/Easy Trials which I have been attending. One of those clubs just happens to be the Bradford Club:- http://www.bradfordtrials.com/index.php?/index Bradford Club Easy Trial last Sunday riding my son's 2003 GG 250 after I broke the gearbox on my 2013 Jotagas 300 :-

I have to agree with that. But I don't agree that the Ossa MAR would tootle along on a small throttle. The ONLY bike I ever had that did that was the Bultaco 325 & 350, hence the reason I loved them. But I much prefer the modern hydraulic clutch & brakes on my JTG300.

My son managed to get in contact with MRS who said it should be around 145psi, so close to your 150psi copemech. Thank you. My son thought it was down on power and suggested new rings. MRS say perhaps RIngs & Piston. It's my wifes Sherco we have just bought for her. I have a Jotagas 300. I've been away from bikes since 1983, so thought the 125 had plenty of power, though not like the JTG.

Hi there. Can anyone tell me the pressure rate for the compression on the 2008/9 125 please? It currently reads 45psi.

Hi just seen your post. Not advertised on here, but it is for sale on fleabay

Thanks for the replies. I find the JTG 300 smooth and responsive when you need or want the power. Not snappy at all. The JTG is also the lightest and agile bike I have ridden so far. BTW. I am 72 this year.

I was just wondering if anyone had ridden both a JTG 300 and a JTG 280 to compare performance? I have a 2013 JTG 300 with 2014 & 2015 updates including 2015 mapping. All standard as far as I know including fast action throttle. Just to say I LOVE the JTG 300. What would the 2014 JTG 280 be like in comparison?

I couldn't agree more. I started back on a Trials bike in 2013 at the age of almost 70 for a few rides after 30 years of NOT riding ANY motorcycle of any kind. Second ride on the 2007 Sherco 290 in 2013 -

Just a point. I don't know whether in this day and age it will be the same? But back in the late 70s and early 80s, we used to have the cylinders done with nikasil after they had seized on our 700 and 750 Yamaha 4 cyclinder 2 stroke sidecar motors. The problem was that they took a LOT of running in to bed them in with new pistons and rings. By which time the rings needed changing again. If you didn't take care running them in, they seized. BUT, the best engine we had was built out of 2 separate non seized but run in 350 twin barrels to make the 700 4 cyclinder. What a motor that was.
