Hi all, i need a little help my new to me gas gas jtx 250 as had a few minor problems. The throttle cable looked to be routed wrong running up the right hand side of the bike and out through the front of the frame with a big loop behind the number board. Can anyone please let know the correct throttle cable route.

Also should the correct spark plug should it be  a BPR5ES Or a BPR7ES as  im getting conflicting information and my old spark plug is unreadable.

 

\Thanks for any help in adavance

 

 

cheers for the info, the new cable as now been fitted run up the left of the frame and around the head stock. And everything feels good  

The stock plug is a #5 but if it fouls easily, go to a #7.  Its a good idea to carry a new,clean plug and wrench (spanner) to change it when it fouls.  Note I did not say if, but when. 

Thanks for the info thats a five, does anyone have a link to a workshop manual as gas gas themselves only have the parts books.

Unfortunately there isn't really any workshop manual.  One of the best resources is the set of youtube videos made by Jim Snell when he was the Gasgas importer.  Search there or on google by his name or even GasGas maintenance and it's easy to find them.  Good luck,  Keep the rubber side down and the feet up!

A little late but maybe think about this. BPR is an NGK. Going from a 5 to a 7 is two ranges colder. If you are fouling plugs with a 5, the 7 will be worse. If you are fouling plugs on a trialer there is some other issue than the plug that you need to fix. Good luck.
