The maniual say's 10mm to 20mm at the longest point I lined my front sprocket ,front swingarm pivot point and rear axle up to make that the shortest point of the chain, and i gave it 10mm up/down total, when i let the bike suspension settle it has 20mm play, 10mm up, 10mm down
so I took the cover of the front sprocket and the front sprocket can be wriggled from side to side. do I just chuck it in gear and give it a tighten?
No ... take it off ... it looks shot to me and I cant see a locking tab on there .. and u should check the spline also .. look to see how many teeth is stamped on it as u want standard gearing on it ..... both sprockets and chain should be replaced all at once
Litetek sell new front sprocket's, most of the JT sprocket's etc are the wrong for the 3LN series bikes
arn't they for 3ln3 up? Whats normally wrong with the jt ones? Are they a good brand. got a price of $215 for front and rear JT sprocket and an o-ring chain.
Correct ... https://litetek.co/Sprocket_Drive_Yamaha_FZR250_3LN3.html Stock gearing is 17t front and 56t rear .... which used to be unavailable so u go 55 or 57 Ive got mine from here before .. JT are fine http://www.rpmmoto.com.au/Store/Spr...250-1986---1993-JT-front-sprocket--steel.aspx http://www.rpmmoto.com.au/Store/Spr...R250-1986---1993-JT-rear-sprocket--steel.aspx http://www.rpmmoto.com.au/Store/Chains/RK/428/428-136-RK-SO-o-ring-chain.aspx
Sorry forgot your's is a 3LN1, but you could run the wider/stepped sprocket from Litetek if you had the step on the outside. Doesn't look like RPM Moto will post oversea's, but i'm sure someone locally could arrange postage for you http://www.rpmmoto.com.au/Helpful-Links/Shipping-Returns.aspx

so finally got this thing back together. put the old chain back on and took it for a strop up the road goes well but the carbs definitely need attention so that's the next mission.
I have an old 3LN Overflow coolant tank I have cleaned out.. it is easy to hang up high out of the road and the outlet is the right size for fuel line. There are specific plastic tanks out there that are not too dear, but I this as the last piece of the FZR parts I had...
I found a 600ml ? Auxillary fuel tank with hose and tap that can hang off your handlebar grip's on ebay for about $12, but cant find a link for it now, was ebay india ? You can get these little tank's cheap, but need an on off tap https://www.ebay.com.au/p/1l-Mini-M...m=253522302289&_trksid=p2047675.c100010.m2109
