my bike has standard engine but has an after market air filter

it also has (wider than standard) sach xtc wheels sach forks an rear swing arm its running sach discs an calipers too but they are off a sach xtc 125 ( the same cc bike as the xvs

i ve had a quote for £146 full comp but that was for the bike in standard form

how much will the above mods effect the above quote are they any custom insurance company i should contact

i d rather declare the mods than risk trouble later but how well do companies look at these things

I wouldn't expect more than £200 from Carole Nash.
