Nothing special about a 12/13, because nothing much has changed over the years. Frames basically all the same, changed to the current round tube in 2009. 2001 to 2008 had a more oval main tube. Check for any cracks around the head tube or any that have been welded up. I think the white framed ones around 2014 had a few frames crack. Steering geometry has stayed the same, unless the triple clamps changed. Forks changed from marzocchi to tech in 2016 i think but the Raga had them a couple years earlier. The marzocchis were a good fork. Same base engine throughout the years, the pro came in 2001. Ignition makes changed over the years so a bit of pot luck regards availability. The Raga/GP were slightly better specced as opposed to the standard/racing, with a better shock (Reiger or ohlins vs sachs) and forks (tech vs marz) and carb (keihin vs dellorto). If you're a clubman i would choose a cleaner standard model over a rougher raga/racing model every time. Id actually stay away from a raga because they have magnesium crankcases that sometimes broke or could be starting to corrode now. Very little difference performance wise. Personally id be looking for anything post 2010. The later frame, and from then the bikes have all been pretty reliable. Earlier years had variable clutch issues. Id pick what looks the best price wise for condition. And dont be swayed by a Raga or GP, unless a similar condition and price I may be slightly incorrect regarding naming, but for many years you had the txt pro and the raga edition. Then when he left i think it became the txt pro and the txt racing. Then they dropped the txt pro (marzocchi and dellorto model) and then had the txt racing and txt GP. Ive had a '10 '12 '15 '17 and a '21

Different ignition. This should be yours

Most likely they went to the rear mudguard light. What years your bike? Is it a txt or a txt pro?

Ive had five 300 ggs since 2010 and never had any problems bar general maintenance, but i know others who have had issues. The montesas are the most reliable. After that i think all the 2 strokes are a much of a muchness when it comes to reliability. They all have their flaws.

Relacing a wheel isn't that difficult especially when you can take pictures of the wheel spoke layout beforehand and also have the correct length spokes. The only measurement you need is the offset from the disc to the rim edge, and its only a trials bike, being a mm or two out isn't that critical. Even if you screw it up i doubt a shop would refuse to correct it for you. You could also replace the bearings, see the below link but if you're unsure about relacing a wheel, that may also be too daunting for you. Basically both wheels have the same outer bearing diameter but different inners for the spindle and different widths. If you can find bearings that are the same outer and width with only the inner difference then its a simple bearing swap. I think the link below contains one set of interchangeable bearing

What are you intending to do on the bike? Ride trails, blast up hills and the odd piece of technical riding to boost your enduro skills? If thats the case the 300 will be no problem for you. But if you intend to rider proper trials, slow speed and tight technical sections, your skill level will dictate that not only could a 300 not be as easy to control as a 250, you won't be good enough (yet) to take advantage of its more power. Theres good trials riders out there riding 250s and in no rush for 300s. 300s are really just reserved for experts. They are nice to bop about on, but in a section they just aren't as nice as a smooth 250. That being said, dont sweat the decision too much, neither will be majorly wrong and only you know what you really want from the bike. You'll find that out after a couple of months

At your size and relative bike ability i would totally rule out a 125. The 250 will be much closer to a 300 than a 125. I doubt you would get on a 250 and complain it hasn't enough power but if you've had a go on a 300 and it felt ok then go for it

If you're serious about him progressing then get a 125, kids flick them about so much better and feel more confident on them. That being said if he just likes riding about and you dont have the intention of him entering events he will probably have as much fun on the 250

i think thats 1990

IMO your lever angle looks ok. Thats what i ride with, but most others would be between that and horizontal. Your lever needs to be closer to the end of your bars. Youre aiming for your index finger to position in the most inward bend part of the lever, ie about the 2 5/8 inch mark on your ruler.

I used my middle finger as a teenager, but got told by everyone to use my index. I agree, now i couldn't use my middle finger through years of index finger use. But it obviously isn't that big of a disadvantage, if even, if guys at the top use it. I always thought mx riders got away with it because you didnt have to be that critical with the clutch but then i seen busto using his. Im certainly not advocating the OP to start trying his middle finger

Liam Everts uses his middle finger too. He must have been taught wrong 😆

Jaime busto uses his middle finger. Ricky carmichael used his middle finger. It works for some

Agreed, the clutch should disengage before the lever hits your other knuckles. I ride with quite a steep decline in the levers while others run them horizontally, some a slight decline, some a slight incline. Then you have the group that use their middle finger for the clutch!!

You need to hold the outer spring and stop it rotating, it helps push the gear back in. Usually the clutch cover is holding it in position

Not sure of the exact o-ring , but epdm is brake fluid resistant

Malcolm rathmells were actually the importers of that model of scorpa. Richard allen does a lot of 2nd hand spares for older bikes, although a clutch hose and seals are just generic parts available from any bike or seal shop

All GG in that era, including 2008 had marzocchis. Those are paioli possibly out of a sherco or beta

Should be the same thats in the PHBL, so should be lots about. Splatshop or allens https://www.splatshop.co.uk/dellorto-phbl-main-jets.html

I can still see it, but the latest post was january, not sure if you mean something more recent has been removed

If you keep snapping chains you are doing something fundamentally wrong, and changing sprockets just so you can fit a stronger chain isn't the best way to go about it. Chain tension too tight maybe

Sounds like you've been thinking this over for a while. Id definitely test ride one before buying, and try to use your judgment (hard i know) that the non replaceable stuff works well and don't worry too much about the general wear and tear stuff as mentioned above

Are you purchasing it purely for the novelty of having a 315? Personally i feel they are overrated, as they were never really the best in class during their time. I feel their slightly elevated price now is just because they are a 2t honda. Don't get me wrong, if you like the bike and want it basically because you want a 315, go for it, but if you have stumbled across it because maybe your budget limits you to an older bike, IMO there are better bikes at a more sensible price than these. The fact you say you are revisiting it, means you had one previously, but its a little unclear what your intentions are. Is it a 2nd bike, or is it going to be your daily driver. Ive a friend who struggled a lot to find gearbox parts for his 315, 5 years ago

Its just the year, or model, starting with A in 1974
