Need help
-
Found out the no spark was to do with the cdi all changed now sparks and start only problem is when I'm sat on it pv won't kick in it bogs and goes to die but on a mx stand stays running hits pv through all the gears and stays running
-
Sounds a bit odd - have you checked for loose connections and that there is no dirt in the float bowl?
-
Yeah you can't really compare the bike running on a stand to having load on the engine.
As soon as you add load to the engine, you are then going to start to see problems.
These sorts of problems could be weak engine, to incorrect fueling.
-
Well I've found something else out it will Rev up in nutral gradually build up revs but at full throttle it won't go past 6k and sound like it's popping
-
How long as it sat fresh fuel? New sparky?
-
Spark plugs brand new and was only sat for around a month but was doing the same thing when I put it in for a mot
-
@vtrn_raptor could be anything that bud but everything can be fixed so get diagnosing put a pic up of spark plug after running the engine for a 10sec's
-
You really want to do a proper plug chop by riding the bike not just running it for 10 mins
-
@nottsbiker Well he can't it's not running right it bogs out and dies.
Sounds like a fueling issue to me.
What's the colour of the plug bud?
Is it smoking heavily?

@nottsbiker this is diagnosing not tuning and it for 10 sec's just enough to see the plug fresh out from running
-
It's smoking a bit and I've checked the plug after trying to ride it for a bit and their was no change in colour this bikes irritating the shit outa me to be fair stands me in about 2500 now and it still won't run right changed piston and rings changed carb changed coil cdi and still won't run right
-
@vtrn_raptor can you not take pictures and videos this all seems vague

I did originally suggest checking the wiring and carb
-
@vtrn_raptor Right, I don't think you're really addressing the problem though.
You need to understand why it's not running right, rather than just swapping components out.
I get the impression, and I could be entirely wrong, that you're changing out components willy
These bikes are so simple, it should only cost a tenth of that to sort this bike out, £2500 would have been a full restoration budget, not "get it running" perse.
As Terry Said, pictures and videos would be so helpful to us, if that's too much then, dare I say it, maybe just take it to a bike specialist. It literally shouldn't cost you that much to get it running.
I feel like you need a better understanding of the core concepts to these bikes, and maybe I suggest reading about two stroke engines in general might help.
You literally should be able to get the engine running sweet on a bench with very minimal tools.
From your vague description, it sounds like a jetting issue. And I don't mean replace the carb, I mean ensure that the end to end system has been installed to factory specifications.
Return the bike back to how it was out the factory, get a haynes manual, look up the specs, get it boggo standard. That's the easiest way to get it running right. Then bolt on tuning parts one at a time jetting accordingly.
-
Well I'm just going to take it somewhere reliable I think and get it done professionally as everything I've replaced was needed and still won't run right so shouldn't cost me much putting into a shop as brought all the expensive stuff
-
@vtrn_raptor do what you think best mate it's a safe option but personally, I think you would be better off doing it your self save a few pounds and have a better knowledge for next time
-
I would do it myself but I literally have no clue what's wrong with it and don't have the money to put it back standard
-
I bet that the shop will also want to put it back to standard to get it running correctly. Ideally you want to use a two stroke tuner / specialist so that they understand the issue and can both diagnose and then solve it.
Many shops these days might not have as much knowledge of two strokes as one was the norm
-
@vtrn_raptor no no no we don't mean buying original exhaust ect we mean to put the carb and a few other bits if you have them back to standard and honestly we understand you don't have a clue at the end of the day it's your bike and your choice but you would really benefit from doing it your self and save money at the same time really it easy just looks hard pal just throw some pics up mate it could be an easy fix you just don't know how it works yet

Is he really saving any money though? I mean if he's spent 2.5k on it and still not solved it, then obviously he's just throwing money away.
Second that though, most shops are going to return it to stock trim to fix it.
I can't see it being anything particularly difficult.
