A few things that spring to mind -
1. check your drive chain is correctly tensioned - a sloppy chain causing gear change issues.
2. check the gear lever linkage isn't worn and flapping about - same as above.
3. will it go in and out of 1st/2nd when the bike is moving, just not easily when your at a standstill..?
4. if the above 1 & 2 are fine, and gear selection is ok when moving then the clutch may be dragging due to a partially worn clutch basket, see below.
This is easy enough to remedy -
1. with the bike on the side stand pop the clutch cover off - put an old rag on the ground below bike to catch any oil.
2. with the bike in gear, using a 10mm spanner undo all 5 clutch spring bolts & springs.
3. using tippex make a line on the top cover plate, clutch plates and basket - this wil enable you to put the plates back in the same position (the plates, basket etc will have all worn together)
4. then remove the top cover plate.
4. then one by one remove the friction & metal plates noting the order they came out - I just thread them on a piece of wire/string so I don't fuckup the order etc)
5. then place an old rag under the bottom of the clutch basket - this will become clear in the nest point.
6. using a small/flat medium or low file remove all the burring on each of the clutch basket fingers - to do this properly will take you an hour or two.
7. thoroughly clean the clutch basket of any metal filings - the old rag you placed under the clutch basket will have stopped any fillings going inside the engine.
8. put all the friction/metal clutch back on the order they came out.
9. put the top cover plate back and springs back on.
10. place some thread-lock on all 5 bolts and do them up to the correct torque setting - if you don't have a small torque wrench then using a 10mm short-throw spanner do them all up till they stop them give them a 1/4 turn.
11. pack out the clutch-arm assy in the clutch cover with some grease, as this will help keep it in the correct position for when you put the clutch cover back on.
If your gear box is fine, the above should fix it. if you don't want to go through the above hassle I have a complete clutch that's already have the above done to it. If the above dosent fix it then the previous owner may have been very rough with their gear changes and possible bent one of the gear selector forks - and that is an engine strip. Unless you know a mate or a very cheap mechanic =- cheaper to buy another engine.
