Head work / Valve Seat Cutting
Posted: Fri Jul 07, 2017 8:40 pm
Hey Team,
Had a rough long weekend with the bike (2007 KTM 250 XCFW). Timing chain skipped and grenaded the whole top end, piston gouged, cylinder gouged, 3 bent valves and the other broke in half, valve seats destroyed.
So...... looking to possibly salvage the head by getting the valve seats recut. There's an old post on here from 2011 with some suggestions but I figured I would see if there was a more current list of preferred machine shops?
The cylinder is the next issue, can a gouged cylinder be repaired? If not where would be a good place to start looking for a new one? Have found a few online but was wondering if there may be spots I should check out first?
Valves, springs, guides, seals and all the goodies in between. Wiseco, kibblewhite, pro x? They all range in price but which would be best to put into my cleaned up or brand new head?
Depending on total costs will determine this bikes fate. If costs for rebuild are to great it will either be parted out or sold as is. What is the better option, selling piece by piece or selling the whole thing as is? Is there a dealer out there that will buy the bike for parts? Either way I'll be scraping pennies to get a new bike as both these options will not get much in return.
If you read all the way to this point thank you.
Your thoughts, opinions and advice will be appreciated.
